The singing of a bird is a complex skill that takes rigorous training like that of a top athlete or musician. Young male birds learn by imitation from their fathers, then hone their skill over months, till their song becomes crystallized in adulthood. A paper in Nature by two scientists at UC San Francisco reported on experiments on the neurobiology of birdsong,1 and found that even adult birds can still learn to modify their singing based on feedback from the environment. It was thought that once a bird’s learned song was memorized, the stereotype was too strong to change. The scientists were able to get Bengalese finches to sing off key by putting white noise into their environment. When the noise was removed, their songs returned to normal. This shows that the childhood memory of the parental song, as well as their own memory of what constitutes normal, allows them to maintain fidelity to the song pattern, while the neurons have enough plasticity to allow adapting to the environment. A write-up of the paper in Science Daily also noted the tidbit that young males tend to experiment more when females are not around. The scientists believe that their findings can help in rehabilitation efforts with human patients who need to re-learn skills lost in aging or injury. If you can teach an old bird new tricks, then there’s hope for people.1. Tumer and Brainard, “Performance variability enables adaptive plasticity of ‘crystallized’ adult birdsong,” NatureThis interesting paper owed nothing to evolutionary theory. The paper did not mention evolution at all. The scientists studied a present-day phenomenon, learned something interesting by observation and experimentation, and produced results that may have practical benefits for people. That’s the way science should be done. In 2008, let’s sing a good-bye to Darwin: “Nevermore” by The Raven.(Visited 15 times, 1 visits today)FacebookTwitterPinterestSave分享0

A resident of Uttar Pradesh’s Meerut district has sought divorce on grounds that his wife, under the influence of a tantrik (shaman), was giving him only ‘laddoos’ to eat.The man approached a family court where he said that on the instructions of the tantrik, his wife gave him four laddoos to eat in the morning and four in the evening. He was not allowed to eat anything else.The man said that he had been ailing for some time and his wife approached the ‘tantrik’ who asked her to make her husband eat only the laddoos.Officials at the family counselling centre were puzzled over the pretext for seeking divorce.“We can call the couple for counselling, but we can not treat the woman for being superstitious. She firmly believes that the laddoos will cure her husband and is unwilling to accept otherwise,” said a counsellor.
The BCCI is under scanner of the Enforcement Directorate (ED) over alleged violation of FEMA during the IPL auctions. The contentious issue is the base fee agreed upon between the BCCI and 72 foreign players. The forex payment guarantees are in clear violation of FEMA or the Foreign Exchange Management Act. Documents obtained by Headlines Today show that the total base fee guarantee extended by the BCCI was worth 13.4 million dollars or Rs 62 crore. The foreign exchange guarantee was given by the board without permission from the RBI. Foreign exchange transactions made during IPL 2 in South Africa too are under the scanner. These transactions were made with entities like Cricket South Africa and the sponsors. The BCCI had advanced 2.5 million dollars to enable budgeted costs of Cricket South Africa. Several transactions made to persons residing outside India and the sources of these funds too are being investigated. Juhi Chawla under scannerMeanwhile, Juhi Chawla, a co-owner of the Kolkata Knight Riders, has come under the scanner for alleged FEMA violation. An ED note accessed by Headlines Today reveals that 40 lakh shares of Chawla were transferred to a Mauritius-based company. The shares were transferred at par in violation of FEMA. The norms stipulate that since the shares were that of an unlisted company, they should have been valued by a chartered accountant. The ED report also cites similar irregularities in Kings XI Punjab and Rajasthan Royals.
zoom As carriers’ stock of ready-to-cascade Asia-Europe containerships is almost empty, the second phase of the cascade could be even more difficult for carriers to manage, according to shipping consultancy Drewry.New Ultra Large Container Vessels (ULCVs) will force the cascade into a potentially more destructive second phase of bigger ships moving into North-South lanes as these vessels will stretch the ability of ports to handle them and trades’ capacity to absorb them without dumping utilisation.The introduction of these leviathans and the proceeding arms race to catch up that has pushed the ceiling closer to 20,000 TEU, has had huge consequences for the industry, one of the biggest being the huge deployment headaches they have given carriers. With the biggest ships effectively locked into the Asia-Europe trade due to port handling limitations elsewhere carriers have had to be creative in shuffling ships into new trade lanes.The phasing of ex-Asia-Europe ships into new lanes has routinely destabilised the new homes and has been a major contributing factor towards persistently low freight rates. The slowdown in demand that coincided with the arrival of the ULCVs exacerbated the industry’s overcapacity and has meant that for years carriers’ deployment decisions were less than optimal, according to Drewry.“Deciding where to use their biggest assets has most often been based on necessity rather than demand,” Drewry said, adding that the average size of vessel on the Asia-North Europe trade is nearly as big as Maersk Line’s E-class units at 14,600 TEU, introduced 10 years ago. There are now only seven sub-10,000 TEU ships left on the route.While the pressure to cascade ships is intensifying thanks to the new ULCVs, carriers in the Asia-North Europe trade now have less low-hanging fruit they can easily pick off and redeploy elsewhere.Since the first quarter of 2013, the average ship size on the Europe-South Africa trade has grown by 92%, while for Asia-West Africa the growth rate was 79% and for Asia-East Coast South America it was 64%. Some of that will have been through newbuilds going directly into the trade, but most will be down to the cascade, Drewry said.

It appears that once again Rufus Ewing and his Government have shown this country that he and his colleagues are not capable or fit to govern.”“The Governor in a Statement issued earlier has said that he will be postponing the date of Election due to the inability of election office officials not having the required preparation time stipulated under the Elections Ordinance and that this decision was made in consultation with the Premier. Whilst the Premier may make a request for the dissolution of the House of Assembly by virtue of section 57 of the Constitution and the date is set by the Governor under the powers given him under section 59 of the Constitution, it is precedent that the Governor entertain the Premier in agreeing the date for General Election.” “No doubt the Premier has had to admit his incompetence and his promise to announce a new date confirms that he had made a confession of same to the Governor. Another history making event for this outgoing Premier, and nothing short of an indication of how he ran this country over the past few years and what you can expect if the country were to unfortunately fall into his hands again.”“Rufus Ewing is the FIRST Leader in our Country’s History to ever get an election date wrong! We assure our supporters that we are more than ready for December 5th or any date to come. We encourage all voters to be patient until the new date is set but to also take note of the PNP’s weak, incompetent leader who has not even gotten the election date right.” “Let’s be all in for a PDM Win!

Liverpool defender Andy Robertson has praised the team’s battling qualities after their 1-0 win at Huddersfield kept their level on points with league leaders Manchester City.The home side gave as good as they got against Klopp’s team, who extended their unbeaten top-flight start to nine games courtesy of Mohamed Salah’s first-half goal.“Yes of course, there’s a bit of relief. It was a tough game against a very good side,” Robertson said, according to Herald. “It’s important you come to these places and you win the game.”“Luckily we managed to get our noses in front and we’ve seen it out from there. We can play a lot better, but they made it hard. It’s a very good three points for us.”Report: City are stunned by Norwich George Patchias – September 14, 2019 Manchester City was stunned by Norwich City in todays Premier League clash.Much has been made in recent days of the potential impact of Aymeric…“We weren’t surprised by Huddersfield at all,” Robertson said. “We did our analysis and in our meetings, the analysis team and our manager were saying they were a better team than the points suggest and I think they proved that.”“They played very well and they’re probably a wee bit unfortunate to be where they are in the table. I think they will have a positive season.””They just need to get up and running and hopefully, they will do that, but for us it was about getting the three points.”“We weren’t at our best, but like I said these are the games you have to win if you want to challenge and we’ll play a lot better.”
John Fitzgerald, director of operations of Channel Airline Airsearch, says the small plane where the Argentinean was traveling might have sunk in less than three minutes.After it was publicly known that a small plane carrying two people disappeared in the English Channel, authorities started looking for survivors.On the plane, Argentinean footballer and recent Cardiff City signing Emiliano Sala was traveling together with the pilot of the aircraft.“If they really are in the water, I would say there is no chance of finding them alive,” said Fitzgerald to Vía País in Argentina.“The other day I went swimming (on the English Channel) and only lasted for three minutes.”“It is very cold in these waters; one person could stay there an hour at the most. I do not think they have landed on land because air traffic would have been informed,” he explained.Sala recently signed for Cardiff City in the English Premier League, after he spent four years with French Ligue A club Nantes.Top 5 best players from the international break weekend Tomás Pavel Ibarra Meda – September 11, 2019 After a fresh international break just came to an end, we need to talk about the Top 5 best players during this whole weekend.We…“I was especially cold. In the first part of the investigation last night, the visibility was good, but we had to deal with the freezing rain that fell around 23.30,” Fitzgerald added.“As the investigation progressed, the cloud ceiling dropped and we had to stop the investigation.”“What we’re looking for first is the device’s black box. If the plane really crashed into the sea but remained in one piece, then you have to pay attention to the traces of oil that come to the surface,” he continued.“If it broke in flight, which can not be ruled out, for one reason or another, then we will find debris on the surface. But an airplane of this size that hits the water sinks in two or three minutes.”La Direction et l’ensemble du Club gardent espoir et c’est toute la famille du FC Nantes qui prie pour qu’@EmilianoSala1 et les autres passagers de l’avion soient enfin retrouvés sains et saufs.#PrayForSala https://t.co/i6POQinWLi— FC Nantes (@FCNantes) January 22, 2019
